Hi,<br><br>I would like to fetch the hourly averages for a particular datasouce in an rrd file for the last 24 hours.<br>The command I'm using is similar to the one on the man page for rrdfetch:<br><br>rrdtool fetch $rrdfile AVERAGE -r $rrdres -e @{[int($ctime/$rrdres)*$rrdres]} -s e-24h<br><br>However, this returns 50 rows, instead of 24. Also is there a way for me just to pull out one datasource, instead of all of them?<br><br>Thanks for any help.<br><br>Ed.<br><br>This is my rrd file info:<br><br>filename =
